SPECIFIC

A

TIONS

• COMPLETE SYSTEM INCLUDES sensor, connecting cable, transmitter, and flow controller

• SENSOR RESPONSE IS PRACTICALLY INDEPENDENT of pH between pH 6 and 10

• NO REAGENTS

• NO AUXILIARY pH ELECTRODE

• VARIOPOL QUICK-DISCONNECT FITTINGS makes sensor replacement easy

1.1 APPLICATIONS AND FEATURES

The FCLi free chlorine system is intended for the

determination of free chlorine (hypochlorous acid plus

hypochlorite ion) in fresh water. Unlike other free chlo-

rine transmitters, the FCLi does not use expensive

sam- ple conditioning systems or messy reagents to

control pH. Nor, does it require an auxiliary pH sensor

for pH correction. Instead, the pH adjustment takes

place inside the sensor, producing a signal that

changes less than 4% per unit change in pH between

pH 6 and

10. Below pH 6.5 the change is less than 1%. The lin-

ear range of the sensor is 0 to 20 ppm (mg/L).

The FCLi is not intended for the determination of total

or combined chlorine (like monochloramine). Nor, can

the FCLi be used for the determination of chlorine in

seawater.

The FCLi uses a three electrode, membrane-covered

amperometric sensor. The sensor consists of a

hydrophilic membrane stretched over a gold mesh

cathode. A silver/silver chloride reference electrode

and an external copper auxiliary electrode complete

the circuit. The fill solution is saturated succinic acid

slurry. During operation, an electrochemical reaction,

driven by the polarizing voltage, consumes free chlo-

rine at the cathode surface. The auxiliary electrode

provides the electrons for the cathode reaction, and

a current proportional to the reaction rate flows

between the electrodes. Because the concentration of

chlorine at the cathode is zero, free chlorine in the

sample continuously diffuses through the membrane

and is destroyed at the cathode. Thus, the cathode

current is proportional to the diffusion rate, which is

proportional to the concentration of free chlorine in the

sample.

The FCLi sensor requires neither sample pretreatment

nor pH correction. All amperometric free chlorine sen-

sors generate a raw current that depends primarily on

the concentration of hypochlorous acid. Because the

fraction of free chlorine present as hypochlorous acid

is a function of pH, readings will be in error if the sam-

ple pH changes from the value it had during calibra-

tion. To correct for pH changes, some manufacturers

treat the sample with acid to convert hypochlorite to

hypochlorous acid. Others continuously measure the

pH and use the pH value to correct the chlorine sensor

reading. The Model FCLi is different. The sensor uses

a highly buffered acidic fill solution for internal pH

adjustment. The fill solution converts all the free chlo-

rine entering the sensor as well as much of the free

chlorine at the outside surface of the membrane into

hypochlorous acid. Thus, the sensor response is prac-

tically independent of pH.

For customers who wish to measure pH, an option

that includes a pH sensor and flow cell is available.

Maintenance is fast and easy. Replacing a membrane

requires no special tools or fixtures. A screw cap holds

the pre-tensioned membrane in place. Replacing the

membrane and fill slurry takes only a few minutes.

The FCLi includes the easy-to-use Model 1056 ana-

lyzer. The transmitter features two fully programmable

4-

20 mA analog outputs. Programming and calibration is

simple and intuitive. The backlit, four-line display

allows the user to read chlorine (and pH) at a single

glance.

Valves, rotameters, and pressure regulators to control

sample flow are things of the past with the Model

FCLi. A constant head overflow sampler ensures the

correct flow to the sensor no matter how much the

sample flow or pressure changes. To eliminate wiring

hassles, quick disconnect Variopol cable is standard.

Stable free chlorine standards do not exist. The chlo-

rine sensor must be calibrated using the results of a

laboratory test run on a grab sample.

2. To keep the transmitter enclosure watertight, install plugs (provided) in the unused cable openings.

3. Install the system in an area where vibrations and electromagnetic and radio frequency interference are

minimized or absent.

4. Be sure there is easy access to the transmitter and sensors.

2.2.2 Sample Requirements

Be sure the sample meets the following requirements:

1. Temperature: 32 to 122ºF (0 to 50ºC)

2. Pressure: 3 to 65 psig (122 to 549 kPa abs)

3. Minimum flow: 2 gal/hr (7.6 L/hr)

2.2.3 Mounting and Making Inlet and Drain Connections

The FCLi is intended for wall mounting only. Refer to Figure 2-2 or 2-3 for details.

A 1/4-inch OD tubing compression fitting is provided for the sample inlet. If desired, the compression fitting can

be removed and replaced with a barbed fitting. Do not remove the check valve. The threads are 1/4-inch FNPT.

The sample drains through a 3/4-inch barbed fitting. Attach a piece of soft tubing to the fitting and allow the waste

to drain to open atmosphere. Do not restrict the drain line.

Adjust the sample flow until the water level is even with the central overflow tube and excess water is flowing down

the tube. Confirm that sample is flowing through the flow cells.

2.2.4 Electrical Connections

Refer to Section 3.1 for details.

2.2.5 Installing the Sensor(s)

1. The chlorine sensor leaves the factory with a shipping membrane in place. The shipping membrane

must be removed and replaced with the chlorine membrane before putting the sensor in service. The

chlorine membrane is in a plastic bag attached to the sensor. Do not remove the shipping membrane

until you are ready to put the sensor in service.

a. Remove the red protective cap from the end of the sensor.

b. Holding the membrane end pointing up (cable connector end pointing down), unscrew the retainer cap

and remove the shipping membrane. See Figure 2.1. It is not necessary to remove the O-ring. Save the

shipping membrane. It should be reinstalled on the sensor when the sensor is not in use.

c. Still holding the membrane end pointing up, install the chlorine membrane. The chlorine membrane is in

the plastic bag attached to the sensor. Screw the retainer back in place.

2. If you are using a pH sensor, remove the protective cap on the sensor.

3. Install the sensors in the flow cells as shown in Figures 2.2 and 2.3. For Model FCLi-02-221, the pH sensor

must be installed as shown in Figure 2.3. The chlorine sensor sits in the flow cell and is held in place by the

union nut. The pH sensor screws into a plastic fitting, which the union nut holds in the flow cell. Be sure to

slip the union nut over the sensor before connecting the cable to the sensor.

4. The Model FCLi is provided with sensor cables pre-wired to the transmitter. Connect the chlorine sensor to

the cable labeled Chlorine Sensor. Connect the pH sensor to the cable labeled pH Sensor. The terminal end

of the sensor is keyed to ensure proper mating with the cable receptacle. Once the key has slid into the

mating slot, tighten the connection by turning the knurled ring clockwise.

NOTE

The chlorine sensor is available in two styles. One has a copper auxiliary electrode; the other has a stain-

less steel auxiliary electrode. The auxiliary electrode is the metal band visible at the bottom of the sen-

sor. The copper electrode is gradually being phased out and replaced by a stainless steel electrode.

If the sensor has a copper electrode…Generally, it is best to keep the sensor in a continuously flowing

sample. The sensor can tolerate loss of sample flow for about four days as long as it remains immersed

in water in the flow cell. A check valve in the sample inlet prevents water from draining out of the flow

cell. If the sensor sits too long in a stagnant sample, copper ions from the air oxidation of the electrode

can diffuse into the sensor. Once inside the sensor, the copper undergoes an electrochemical reaction

that greatly increases the background current and can potentially damage the sensor. See step 2 in

Section 6.3.2 for more information.

If the sensor has a

stainless

steel electrode…The stainless steel electrode is not susceptible to air oxi-

dation. Therefore, loss of sample flow does not normally present a problem.

Do not expose the chlorine sensor to air for any longer than an hour. Prolonged exposure to air will cause

the membrane to dry out. Once this happens, the membrane must be replaced.

RISK OF ELECTRICAL SHOCK

Electrical installation must be in accordance with the National Electrical Code

(ANSI/NFPA-70) and/or any other applicable national or local code.

3.1.1 Power

Wire AC mains power to the power supply board, which is mounted vertically on the left hand side of the analyz-

er enclosure. The power connector is at the top of the board. Unplug the connector from the board and wire the

power cable to it. Lead connections are marked on the connector. (L is live or hot; N is neutral, the ground con-

nection has the standard symbol.)

AC power wiring should be 14 gauge or greater. Run the power wiring through the conduit opening nearest the

power terminal. Provide a switch or breaker to disconnect the transmitter from the main power supply. Install the

switch or breaker near the transmitter and label it as the disconnecting device for the transmitter.

3.1.2 Analog output wiring

Two analog current outputs are located on the main circuit board, which is attached to the inside of the enclosure

door. Figure 3-1 shows the location of the terminals. The connectors can be detached for wiring. TB-1 is output 1.

TB-2 is output 2. Polarity is marked on the circuit board.

For best EMI/RFI protection, use shielded output signal cable enclosed in earth-grounded metal conduit.

Keep output signal wiring separate from power wiring. Do not run signal and power or relay wiring in the same

conduit or close together in a cable tray.
